VENTILATINGeCHIMNEY.

SPECIFICATION forming part of Letters Patent No. 314,309, dated March24, 1885.

App'ication filed April 30, X884. '0 moth-1.)

To 610% whom at may concern:

Be it known that I, SAMUEL TQATKIN, of Georgetown, in the county ofWilliamson and State of Texas, have invented a new and In provedVentilating-Chimney, of which the following is a full, clear, and exactdescription.

The object of my invention is to provide a new .and improvedventilating-chimney and flue-stopper which can also be used with brick1o fines.

The invention consists in various parts and details and combinations ofthe same, as will be fully described and set forth hereinafter.

Reference is to be had to the accompanying I5 drawings, forming a partof this specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure l is alongitudinal sectional elevation of my improved combinedventilating 2o chimney and flue-stopper, parts being broken out. Fig. 2is a plan view of the under side of the flue-stopper. Fig. 8 is a planview of the bottom edge of the ventilating-pipe.

A thimble, A, orshort neck of cast or sheet 2 metal is provided with aseries of outwardlyprojecting or radial lugs, B, which are formed orsecured on the said .thimble such a distance from the upper end thatwhen the said lugs B rest on the upper surface of the floor O the bottomedge of the thirnble will project a short distance from the ceilingformed by the under surface of the floor. The said thimble A is providedin its bottom edge with a series of notches, D, which can have anydesired shape.

From theinner surface of the thimble A two or more lugs, E, projectinward, which are provided with screw-threaded apertures. A circular orother plate, F, has its rim bent up to form an annular flange, G, in theedge of which notches H are formed.

Screws J are passed up through the plate F and are screwed into theapertured lugs E, thus holding the plate F to the lower end of thethimble and pressing the edge of the flange 5 G against the ceiling G.

The plate F is provided with a central aperture, K, around the rim ofwhich an upwardly-projecting flange, L, is formed, and to'the saidflange the lower end of a pipe or flue, M,

is riveted, which extends up through the roof and hes its upper end, theedge of which is tongued, bent outwardly over the neck N of an annularhood, 0, which neck rests closely against the outer surface of the flueM.

The hood 0 is provided in its inner surface with two or more downwardlyprojecting prongs, P, which rest on the upper end of a tube or flue, Q,surrounding the tube or flue M concentrically, the lower end of the tubeor flue Q being riveted to the upper end of the 6o thimble or sleeve A.

Outside of the neck end of the hood 0 a tube, R, is placed, which is tobe surmounted by a cowl or like device.

The tube Q is surrounded by a rain-proof, S, secured to the roof, whichrain-proof consists of a tapering tube provided at its bottom withflanges seen red to the roof. In place of surrounding the tube M by .thetube or metal flue Q it can be surrounded by a brick 7o flue which setson the floor 0; but about ten inches of the tube Q and about eightinches of the tube M must remain to makeathimble.

To the under su rface of the plate F four gates or wings, T, are pivotedin such a manner that they can cover the opening K in the plate F, theend edge of one gate T resting against the inner side edge of the other,as shown in Fig. 2. When the flue is not being used that is, when nostow-pipe is passed through the opening K in the plate E into the lowerend of the pipe Mthe said opening K is closed by means of the pivotedgates T. If the flue is to be used, the gates T are swung from the holeso as to leave the same entirely free. The gates T form the cover forthe flue when the same is not in use, and as the said coversor gates arehinged and affixed to the plate F the inconvenience and trouble causedby misplaced and lost fluecovers are avoided by using 0 my impro'vedventilatingchimney and fluestopper.

The hot air of the room passes through the notches H, formed in theflange of the plate F, through the notches D,-and up through the annularspace between the concentric tubes M and Q, and passes off throughopenings WV of the tube Q. The hood 0 prevents rain and snow from beingdriven into the openings W", and the rain-proof S prevents the waterfrom being driven down on the outsideof the tube Q.

Having thus fully described my invention, 1

claim as new and desire to secure by Letters I inwardly projectingapertured lugs E, the

Patent 1. The combination, withthe smoke-flue M, of the ventilating-flueQ, surrounding it, the thiinble or sleeve A, to which the lower end offlue Q is secured, the plate F, adjustably and removably connected tothe lower end of thimbleAand provided with a notched flange, G, and anopening, K, said plate F being secured to the lower end of thesmoke-flue M in line with the opening K, whereby the plate F and thesmoke-flue M may be readily removed without disturbing the sleeve A orflue Q, and may be adjusted to different thicknesses of ceilings,substantially as set forth.

2. The combination, with the smoke-flue M, of the ventilating-flue Q,the thimble A, provided with outwardly-projecting lugs B and on thelower end of the thiinble A, and proo vided with a central aperture, K,substantially as herein shown and described.
